A researcher conducts two studies on self-perception.In Study 1,24 participants rate how positively they view themselves (on a 5-point scale)in one of three groups (n = 8 per group).In Study 2,the researcher conducts a similar study,except that k = 3 and n = 8.If SS_BG = 28 and SS_E = 42 in both studies,then in which study will the decision be to reject the null hypothesis at a .05 level of significance for a one-way between-subjects ANOVA? A) Study 1 B) Study 2 C) both D) none

The decision to reject the null hypothesis in an ANOVA depends on the F-ratio, which is calculated as the ratio of between-group variance to within-group variance. Given that both studies have the same sum of squares between (SSB) and sum of squares error (SSE), the F-ratio would be the same, leading to the same decision regarding the null hypothesis in both studies.
